WATER-SUPPLY CONNECTION.

l Application filed January 7, 1924; Serial No. 684,720.

To all whom it may concern:

Be it known that I, JAMES A. Moon), a

which were either complicated, difficult toconstruct, expensive to manufacture, or so citizen of the United States, residing at Milheavy as to add unnecessary weight to the waukee, county ofMilwaukee, andState of lVisconsin, have invented newand useful Improvements in Water-Supply Connections', of which the following is a specification.

This invention relatescto improvements in water-supplyconnections for outboard motors of the type in which; reversal is accom plished by a bodilyfiotative,movement of the propeller and related "parts about the axis of the upright driving shaft therefor. It will be un'derstoodthat the ordinary outboard motor includes an internal com- 'bustion engine, the power of which is transmitted through a vertical drive shaft .to a horizontal propeller shaft and a propeller carried thereby. The' propeller' shaft and propeller, together with gearingfor con- \necting the-propellerv shaft and drive shaft, are usually supported by means of a tubular housing for-the vertical drive shaft. Such an arrangement of parts is shown in the patent to Evinrude,'-No. 1,001,260, dated August It has always been more or less of a problem to provide water for the cooling of an internalcomb'ustion engine such as is disclosed in the above mentioned patent. This problem is intensified when the construction of the outboard motor includes a bracket having rearwardly projecting arms for the adjustment of the motor in a vertical plane while .preserving the rotative character of the drive shaft housing. Such a bracket is disclosed in Patent No. 1,236,7 35, issued to G. J. Meyer, August 14, 1917. It will be understood that if water supply connections are led from a point beneath the water line to the cylinders of the motor, it is not only,

possible but probable that such connections may become entangled with the arms of the bracket and may become broken or otherwise damaged.

Various expedients have been devised in an attempt to overcome the difficulties above noted, but, so far as I am aware, all of such expedients have involved constructions device. 1

therefore toprovide a novel and direct wa-' tor-connection between a submerged pum and the engine cooling jacket and to lea such connection past a hearing at the bracket arms above referred to without a compli- 6o cated, expensive, or heavy construction.

More specifically stated, it is the object of this invention to provide a water supply connection within the radius of the drive shaft housing and yet exterior to said housing so that the water pipe will be accessible for its initial placement, replacement, or repair, and will not be subject to damage by frictional contact with the drive shaft.

Another difliculty heretofore experienced with such water supply connections as have been introduced into the interior of the drive. shaft housing has consisted in the possibility of water leakage occurring to dilute lubricant in the propeller'gear case supported by said housing. It is, therefore, an object of this invention to lead the water pipe through a bearing which receives said housing without using a construction requiring the perforation of the housing. As will apso pearliereinaftcr, the device herein-disclosed is so constructed that the drive shaft housing is imperforate throughout its length and .is therefore not subject to water leakage.

Figure 6 is a section taken on line 66 of Figure 5.

Like parts are identified by the same reference characters throughout the several represents the jacketed cylinder, 6 the crank case, and 7 the fly wheel. The engine is supported for pivotal movement in a vertical plane about the pivot pin 8 which connects it with bracket 9. This bracket is adapted to engage the transom of a boat in the usual manner and is provided with a downwardly extending portion 10 from which project spaced arms 11.

Connected with the fly wheel 7 is an upright drive shaft 12 which extends down wardly between arms 11 and is encased by a tubular shaft housing 13 which likewise extends between said arms and finds a bearing in a block 14 which is adjustable between the arms to a plurality of predetermined positions, whereby to control the angular setting of the motor upon its supporting pivot pin 8.

The shaft housing 13 supports a propeller gear casing 16 withinwhichis journaled a propeller shaft 17 for the support of propeller 18. The housing 16 carries a pump casing 19 having an inlet portion 20, the pump plunger being preferably driven by a cam on vertical drive shaft 12 after the manner disclosed in the application of James A.

re arwardly the Mould, filed March 5, 1923, Serial No; 622,739. The particular construction of the pump is unimportant, however.

The delivery pipe 22 of the pump extends upwardly therefrom and thence radiall in- .wardly toward the housing 13. It wi 1 be understood that this housing and all related parts, including the pump, are not only mounted for oscillation upon a vertical axis responsive to the movements of tiller handle 24 but also that the housing and the submerged parts carried thereby may be rotated .bodily. through 180 independently of the tiller upon their release from the tiller through some mechanism similar to that disclosedv in the atent to C. J. Meyer, No. uly 18, 1916. With such mechanism, when it is desired to operate the motor in a forward direction after it has once been reversed, the housing is again released and travels. through an additional 180 are, thereby completing a single revolution, about the vertical axis of the drive shaft. Under such circumstances it will be obvious that unless special provision is made to lead the water pipe past bearing block 14 such pipe'would become hopelessly entangled in the block or in the arms 11.

In the preferred embodiment of this invention, the wall of shaft housing 13 is longitudinally indented to provide a vertically extending groove such as that indicated at 25. This groove is made of sufficient depth to receive bodily a pipe 26 so that the exterior wall of the pipe is wholly with'in the'ci'rcumference of a circle including the undented portions of the wall of the housing. In other words, the tube 26 is located wholly within the radius of the housing wall.

At the lowerend of the inlaid tube 26, the longitudinal channel, shown at 25 to receive said tube, is preferably filled about the tube by solder, or otherwise, in the manner indicated at 27 in Figure 3. Secured about the shaft housin at this point is a two-part clamp, incluc ing the generally semi-circular elements 28 and 29, which may conveniently be held together by cap screws such as that shown at 30. The solder which is filled into channel 25 about the lower end of tube 26 will make a water-tight joint between the end of said tube and the clamp. Suitable packing may be interposed between clamp section 29 and the solder at 31, if desired. The lower portion of clamp section 29 will preferably bear, through'the packing 31, di-

rectly upon the wall of housing 13, no solder being necessary at that point.

Clamp section 29 may be provided with a nipple 32 adapted to receive the inwardly directed end of pipe 22, and have threaded thereto a nut 33 for effecting the usual coupling between these parts. Thus, the water delivered from pump casing 19 is directed into a vertical pipe 26, which is not only wholly within the radius of the shaft housing wall, but is nevertheless external to the indented portion of saidwall so that it is very readily accessible and can easily and cheaply be set in place.

Attached to the crank case 6 is a housing 35 which contains the latch mechanism for the release of shaft housing 13 for reversing It will be noted that the channel 25 in' shaft housing 13 extends well upwardly into the sleeve portion 38. The channel about the upper end of tube 26 is preferably filled in with solder in the manner. indicated at 27 ring or annulus 42 provided with apertures at 43 for water deliver therethrough. This annulus divides cham centric compartments, the inher of which is adapted to receive water directly from tube 26 and the outer of which is adapted to deliver such water through port 44 to the .pipe 45 which leads from sleeve portion 38 to the cylinder jacket. Packing may be used at 46 and 47, if desired, to ensuTe that the joints on either side of the lantern ring 42 will be tight.

As has already been indicated, the sleeve portion 38 is directly connected with the crank case and thereby with the cylinders so that the pipe 45. may be wholly inflexible. These parts all oscillate together within the supporting member 37 for steering purposes, and the shaft housing 13 is released through the mechanism in housing 35 for independent rotation when it is desired to reverse the motor. At such times as the motor is in reverse the tube 26 will deliver water to the opposite side of lantern ring 42 so that such water will have to traverse 180 of compartment 39 before reaching the outlet port 44.

In Figures 5 and 6 I have illustrated an other modified construction, showing an application of this invention to a known structure. Figures 5 and 6 show a construction which is disclosed in the co-pending application of James A. Mould, executed of even date herewith, and entitled Anti-tilting lock for reversible outboard motors. In

' this construction a semi-tubular bearing block 50 takes the place of bearing block 14. The semi-tubular bearing block 50 opens v rearwardly as is clearly shown in Figure 6. It is provided with an upwardly extending ear 51 provided with an aperture 52, whereby the bearing block may be positioned at any desired point between arms 11. At its upper end the bearing block 50 is provided'with a concentric enlarged portion 53 upon which is fastened a semi -annu lar cap 54 having a depending sleeve 55 immediately adjacent the shaft housing 13. Clamped to the shaft housing 13 is a sleeve" 57 axially cut at 58 and provided upon either side of the cut with ears such as that which is shown at 59. By means of these ears, which are apertured at 60, a bolt may beutilized to clamp the sleeve in any desired position upon the shaft housing. The sleeve carries at its upper and lower ends annular flanges 62 and 63, respectively. As disclosed in the application above referred to, means is provided for lifting the entire shaft housing, with the shaft and operating (parts, at.

the moment the shaft housing an related parts are released for independent rotation for reversing purposes. When the shaft housing is thus lifted the sleeve 57 being r 39 into two con-' clamped thereto, will be lifted therewith and the annular flange. 62 will be engaged with the relatively stationary semi-sleeve 55carried by block 50. The flange 63 will simultaneously engage the lower end of the semitubular block. Due to this engagement, which is effected at the moment of reversal, the motor is prevented from being tilted by the rearward thrust of the propeller, although, with the parts inthe position indicated, the motor is free to tilt if a submerged obstacle is encountered. It will be noted that the construction illustrated corresponds, so faras the disposition of tube 26 is concerned, with that disclosed in Figure 2, the principal diflerence being that the bearing surface between the shaft, housing I and block 50, instead of being formed ditail herein. It is merely desired to bring out that where a supplemental bearing blobk, such as that shown at 57, is employed, I

and which is not of sufliciently greater 'ra.

dius' that the shaft housing to permit it to carry tube 26 exterior of the shaft housing, the tube may be located within the groove or depression of the shaft housing in the manner indicated in Figures 5 and 6.

It will be clear from the foregoing description that all of the devices herein disclosed are extremely easy of application while accomplishing effectively the purposes for which they are designed. Each device is adapted to make possible the use of standard parts, and each device is adapted to lead the water pipe through a bearing in block 14, or '50, without danger of entangling the water supply connectionsin the arms 11 during motor reversal. The disposition of the water pipeillustrated in Figures 1 to '6, inelusive, is'such, furthermore, that it not only enables; the use of a standard bearing block at 14V (or at 50) and a bracket, having arms 11',spaced at th'e'usual distance apart, but

also makes it possible to dispose tube 26 in such a position that it is, fully protected from the'danger of injury or entanglement with objects encountered in thewater.-

outboard motors are frequently operated in shallow streams and. in waters where snags and submerged obstacles abound, the mpor tance of-a construction in which the water supply connections are protected agamst entanglement will be obvious.
